  'Display' menu help page


  The 'Display' menu contains the following sub-menus:

  'Select data':
      Select the data array to display (image, PSF, background,
      detected stars, synthetic field, other files).

  'Options':
      Modify the display options of the currently displayed data
      array. If the displayed array is a 'global variable' (image,
      PSF, background, detected stars, synthetic field), the new
      display options become the current options for the array
      itself.
